Hi All,

I just had to share pictures of my new toy.

It worked slick for rebuilding the injectors on my 240D. I splurged and found the test guage on eBay (...could never have justified full price...). It's not fluid filled, but the graduations are every 10 PSI - works great! And the hydralulic pump is a max 2850 PSI (~200 bar) too. I had another set of spare injectors so was able use shims to balance all well within spec; car runs great!

Thanks to all who shared their experience on building their own!

Cheers,
Andy

Looks very professional.

The Factory Made Nozzle/Pop Testers do not have Liquid Filled Gauges. But, they have a valve that isolates the gauge so you can work the handle and get the air out without damaging the Gauge.

I think yours has that vlave also.

Yes, I saw one of the forum members had put a one way flow control valve just before the guage. The pressure relief valve on the pump itself backs off the pressure ok, but in addition, the flow control can ease the needle back down to zero more smoothly.

Looks good ! The canister on the back is for filling with diesel and checking level ?

Yes, that's correct. I actually had it left over from another project and put it to use (...New England packratting skills put to use...). It also acts like an expansion reservior for when you back off the pressure, so the level varies slightly in use. It's a bit of a pain to get fuel funnelled into it, but since very little fuel is used when testing it's not too bad.

I tried the home brew model using a cheap bottle jack some years back. I did manage to make it work for about 10 injectors. I was pumping it up and heard a squealing whistle and "found" a crack in the little pump section. Yours looks a lot better.

Thanks Sean. I appreciate the kudos, especially from your area of expertise!

Rebuilding the injectors was a fun project and very rewarding being able to use the homemade tester.

... hmmm, now on to pull the injectors out of my 300D parts car to play with...

That's a SWEET application!
Can you tell us where you got your parts? Is that a Harbor Freight pump?
Thanks,
Dan

Hi Dan,

No, the pump was an eBay item too as well as the flow control valve. Enerpac is one manufacturer for these type of pumps for auto body type work. This one is model P-18. I had been looking for some time and comparing various hydraulic hand pumps. This one just happens to be a "low" pressure unit (2850 PSI). Most others are rated for around 10,000 PSI; not that those wouldn't necessarily work too (I guess). I ordered the fittings from McMaster Carr to put it together and had a spare set of injector lines, one of which was volunteered to finalize the job.

I figure I have about $250 invested into parts I purchased off eBay. Just the guage (new) from McMaster is more than that itself. I've seen homemade testers with the smaller, fluid filled guages, but held off until I came across this one.

Thanks,
Andy
